Defensible email and document collection from Microsoft 365 and IMAP. Built for litigation hold, regulatory response, and HR investigations.
Krellix · MMXXVI
Built for the people who need the evidence — not the people who manage the tenant.
Krellix builds tools for solo and small-firm legal professionals who need evidentiary-grade preservation without enterprise infrastructure. Our flagship product, Krellix Mail, collects email and documents with full chain of custody — hashes, RFC 3161 timestamps, a verifiable manifest. The next products will follow the same principle.
01Local processing — collected data never leaves your machine
02No enterprise license required — runs on Windows you already own
03Open formats only — .eml, PDF, plain-text manifest
§ 02/The suite
Krellix builds one product at a time, deeply. Mail is in operators' hands today. What ships next will be shaped by the customers who use Mail first.
Customer-driven. The fastest way to influence what we build next is to be the customer who needs it.
§ 03/Why Krellix exists
Most small firms and mid-market companies don't have Microsoft Purview. The moment a matter requires preserved email, the options narrow to three: forward messages to yourself (inadmissible), ask IT to PST-export them (no chain of custody), or call a vendor and wait two weeks for a five-figure invoice.
Krellix is the fourth option. Annual license, runs on the operator's machine, produces native .eml files, searchable PDFs, a signed manifest, and a public RFC 3161 timestamp.
The defensibility argument is verifiable on any machine, by anyone — including opposing counsel. The same self-running verification script is in every export. No Krellix license required to verify what Krellix produced.

Every export is a sealed artifact.
The seal verifies on any machine, by anyone, forever.
§ 04/Who Krellix is for
Preserve client correspondence at the start of a matter without sending it to a vendor. Most Krellix exports cost less than one billable hour.
Your company has Business Premium, not E5 Compliance. Krellix gives you the defensible collection that Purview would — without the $57/user/month license.
Preserve email surrounding a conduct investigation before custodians know they're under review. The manifest documents the chain of custody; your legal team can attest to it.
Regulated industries need ad-hoc preservation for SEC, FINRA, OCC, and HIPAA responses. Krellix produces a defensible export without procurement for a full eDiscovery platform.
§ 05/Where Krellix is today
Real product, real customers, full chain of custody — hashes, RFC 3161 timestamps, verifiable manifest.
Working with a small number of customers in Kentucky and beyond, expanding deliberately rather than chasing scale. Every customer talks to the founder directly.
The roadmap is public so you can see where Krellix is heading before you commit.
